• Code: C-5307#
• Description: The rotation of the cooling fan /3 (FM6) is checked and +24V power source is also checked. An abnormal condition occurs with the FM6 EM signal a specified period of time after FM6 turns ON. This abnormal condition recurs even a specified period of time after FM6 is turned OFF and then turned ON, and an error detection signal (24V cut off) is detected.
• Causes: Confirmation of the wiring harness and the connector Cooling fan /3 (FM6) AC drive board (ACDB) Printer control board (PRCB) DC power supply /2 (DCPS2)

• Code: C-5308
• Description: The blowout of ICP for the cooling fan /3 (FM6) in the AC drive board (ACDB) is checked. An abnormal condition occurs with the FM6 EM signal a specified period of time after FM6 turns ON. This abnormal condition recurs even a specified period of time after FM6 is turned OFF and then turned ON, and an error detection signal (blowout of ICP) is detected.
• Causes: Confirmation of the wiring harness and the connector Cooling fan /3 (FM6) AC drive board (ACDB) Printer control board (PRCB) DC power supply /2 (DCPS2)

• Code: C-5309
• Description: Rotation of the cooling fan /3 (FM6) is checked. An abnormal condition occurs with the FM6 EM signal a specified period of time after FM6 turns ON. This abnormal condition recurs even a specified period of time after FM6 is turned OFF and then turned ON, and an error detection signal (24V cut off/blowout of ICP) is not detected.
• Causes: Confirmation of the wiring harness and the connector Cooling fan /3 (FM6) AC drive board (ACDB) Printer control board (PRCB) DC power supply /2 (DCPS2)

• Code: C-5310
• Description: When the print is started, an error detection signal of the cooling fan /1 (FM26) or the cooling fan /2 (FM27) is detected.
• Causes: Confirmation of the wiring harness and the connector Cooling fan /1 (FM26) Cooling fan /2 (FM27) AC drive board (ACDB) Printer control board (PRCB)

• Code: C-5311
• Description: When the print is started, an error detection signal of the cooling fan /3 (FM6) is detected.
• Causes: Confirmation of the wiring harness and the connector Cooling fan /3 (FM6) AC drive board (ACDB) Printer control board (PRCB)

• Code: C-5312
• Description: An abnormal condition occurs with the FM10 EM signal a specified period of time after the ADU cooling fan /1 (FM10) is turned ON. This abnormal condition recurs even a specified period of time after FM10 is turned OFF and then ON again, and an error detection signal (24V cut off) is detected.
• Causes: Confirmation of the wiring harness and the connector ADU cooling fan /1 (FM10) ADU drive board (ADUDB) DC power supply /2 (DCPS2)

• Code: C-5313
• Description: Rotation of the ADU cooling fan / 1 (FM10) is checked. An abnormal condition occurs with the FM10 EM signal a specified period of time after FM10 is turned ON. This abnormal condition recurs even a specified period of time after FM10 is turned OFF and then ON again, and an error detection signal (24V cut off) is not detected.
• Causes: Confirmation of the wiring harness and the connector ADU cooling fan /1 (FM10) ADU drive board (ADUDB) DC power supply /2 (DCPS2)

• Code: C-5314
• Description: An abnormal condition occurs with the FM11 EM signal a specified period of time after the ADU cooling fan /2 (FM11) is turned ON. This abnormal condition recurs even a specified period of time after FM11 is turned OFF and then ON again, and an error detection signal (24V cut off) is detected.
• Causes: Confirmation of the wiring harness and the connector ADU cooling fan /2 (FM11) ADU drive board (ADUDB) DC power supply /2 (DCPS2)
